Modulation Methods

We have a low frequency signal and want to send it at a high frequency, for this modulation is required.
“Modulation is the process of superimposing the low frequency signal onto the high frequency signal”.

Modulation Schemes

There are three modulation schemes are available:

Amplitude Modulation (AM)

Amplitude Modulation is the amplitude of the carrier varies in accordance to the information signal

Frequency Modulation (FM)

Frequency Modulation is the frequency of the carrier varies in accordance to the information signal

Phase Modulation (PM)

Phase Modulation is the phase of the carrier varies in accordance to the information signal
